IRRITATION AND

DISCOMFORT:

When you heat your

home, indoor humidity

levels fall below the

optimum range. This

causes you to experience

the discomforts of too dry

itchy skin, annoying static

shocks and being too cold

at normal temperatures.

UNHEALTHY AIR:

Viruses thrive in low humidity

conditions and can actually

increase the likelihood of

getting colds, flu and other

upper respiratory ailments.

The American Society of

Otolaryngology advises

the importance of preventing

an overly dry environment

because it significantly

increases susceptibility

to infection.

HOME DAMAGE:

When heated air isnt

properly humidified, it

causes walls and ceilings

to crack and wood floors

and trim to separate.

Expensive musical

instruments can go out

of tune and electronic

equipment can fall victim

to static electric charges,

requiring expensive repair

or replacement.

HIGHER ENERGY COSTS:

Dry air robs the moisture

from your skin, making you

feel colder, which means

you turn up the heat. Dry

air also shrinks the framing

around doors and windows,

resulting in gaps that let in

cold air from the outside,

making your home less

energy efficient.

The air inside your home is drier than you think.

Heating your home dries out the air. The resulting dry air absorbs moisture fromyou and everything inside your home. Even newer, tighter built homes will

succumb to the negative effects of air that is too dry.

Every home needs a humidifier.

Relative Humidity (RH) indicates the amount of water vapor, in percent, actually in

the air compared to the maximum amount that the air could hold under the same

conditions. The warmer the air, the more moisture it can hold.

Air in the home heated to 70 F can hold about eight grains of moisture per cubic

foot. That is 100% RH. If there are only two grains per cubic foot in the home, this

is 1/4 of the air capacity or 25% RH.

So, what happens to the air when its heated? Your furnace will bring in outdoor

air to be heated. During the winter months its very common to find outdoor RH at

70% and air temperature at +10 F. When this air is heated to 70 F, the indoor RH

drops to 6%, this is similar dryness to desert conditions. The only solution is to

add water vapor to the air humidification.

Your home could be as dry as the Sahara Desert!

Enjoy the benefits of whole-home humidification

PROVIDE TOTAL comfortHeating your indoor air dries out your skin. This not only makes

you feel itchy but can also make you feel chilly.

This cold effect is not the only discomfort caused

by too dry air. Annoying static electricity is

another indication of low humidity levels. Proper

relative humidity (RH) will reduce this discomfort.

Aprilaire whole-home humidifiers provide

maximum comfort throughout your entire homeevery hour,

every day, all season long, without the mess and inconvenience

of portables.

HELP PROTECT YOUR FAMILYS healthAir that is too dry can make you more susceptible to catching

cold or flu viruses. How? Dry air dries out your nasal

membranes and makes the lining of your nose more susceptible

to bleeding and infections. Also, low levels of humidity have

been linked to the speedier progression and transmission ofviruses in the air*.

Proper humidity is a key factor to staying healthy

in winter. By keeping your sinuses and airways

moist, you reduce the potential for bacteria and

viruses to enter your body. Aprilaire humidifiers

are proven most effective at providing optimum

levels of humidity.

Preserve YOUR HOME AND FURNISHINGSThe addition or reduction of moisture drastically affects the

qualities, dimensions, and weights of many materials.

For example, wood, leather, paper, and cloth all contain water.

Paper, plastic, cloth, fibers, glue, skin and practically everything

else in the home shrink as they lose water, and swell as they take

on water. If the water loss is rapid, warping and cracking can

take place. As the RH changes, the condition and dimensions of

the materials change, as constantly as the weather. This is why

humidity must be added and controlled.

Furniture construction is affected as glue dries out, joints

separate, and cracks appear. Plaster and drywall dries out,

pianos, organs, and other musical instruments lose their tone.

Pieces of art, books, and documents dry out and can break or

crack.

Your home and its furnishings make up

what is likely your largest investment.

By providing constant humidity contro

Aprilaire humidifiers help to keep them

in good condition, maintaining

their value and extending their life.

SAVE MONEY ON energy BILLSStudies suggest approximately 74% of a homes infiltration

occurs at the homes envelope (perimeter walls, windows, and

doors). A published study indicates the framing around doors,

windows, etc., will have less shrinkage when the proper inside

RH is maintained. Therefore, proper inside RH may reduce

infiltration of outside air, because the cracks between the

framing and the supporting structure will be reduced. With

minimum shrinkage, there is less crackage, reducing infiltratio

thus increasing energy conservation.

An Aprilaire whole-home humidifier

also allows you to feel warmer at

lower thermostat settings. The U.S.Environmental Protection Agency

reports that you can save up to 4% on

your heating bill for every degree you

lower your thermostat.

Humidification, the process of adding moisture to the air, is one of the most important aspec

of total indoor comfort, yet its one of the least understood. One reason is that humidity is an

intangible. It cant be seen, touched, or smelled. It has no color, no sound. However, its presen

when controlled properly, offers many proven benefits.

^NOTE: Heat pumps Model 400 can be installed in heat pump applications. However, due to the fact that heat pumps deliver lowertemperature air to the home than gas furnaces, evaporation will be approximately 60 % of rated capacity. (With other Aprilaire models hotwater can be used instead of cold to maximize evaporation. However, due to the nature of the wicking water panel in the Model 400 hot waterprovides no extra benefit.) As such, your dealer will need to take the size and age of your home into consideration to ensure the Model 400will provide satisfactory comfort and protection through adequate humidification.

* = Automatic Digital Control (shown)**M = Manual Control For those rare occurrences where an automatic control is not practical, Aprilaire digital control can be installed in manual mode, while still delivering the accuracy and

information you need for optimum performance.

Warranty All Aprilaire models are warranted for five (5) years from date of installation for parts.Heat Pumps Plumbing the humidifier to hot water is recommended on all heat pump installations or if it is installed to operate independently of a call for heat. (See^NOTE for Model 400)Bypass humidifierscan be installed on the supply or return plenum.

Water feed rate for the Model 700, 350, and 360 is 6 gph; the Models 500 and 600 is 3 gph; Model 400 is .7 gph: Model 800 is .6 gph when connected to 120V, 1.1 gph when connected to 208V and1.18 gph when connected to 240V. (gph = gallons per hour)

Evaporative capacities assume blower active 100% of the time, and plenum temperatures at 120F and cold water.
